BALTIMORE--(BUSINESS WIRE)--Millennial Media (NYSE: MM) announced today that company founder and CEO
Paul Palmieri has resigned from his post as CEO and from its board of
directors effective immediately. Mr. Palmieri will join New Enterprise
Associates (NEA) as Venture Advisor focused on technology out of its

“Some time ago, I expressed my desire to the board to transition out of
the company, and return to working with early stage entrepreneurs,” said
Palmieri. “The board and I worked collaboratively as it sought to
identify a strong CEO for the next phase of the company’s growth. I’m
excited about the company’s future, and confident of the team’s ability
to continue executing on our vision to transform advertising through
mobile.”

To replace Palmieri, Millennial Media announced today the appointment of
Michael Barrett as CEO and member of its board of directors. Mr. Barrett

media, having served as Chief Revenue Officer at AOL and Fox Interactive
Media among other executive leadership roles.

“Paul Palmieri has demonstrated masterful entrepreneurship in taking
Millennial from a concept, through competition, growth, scale, and
transition to a fast growing public company and leader in its industry,”
said Patrick Kerins, General Partner, NEA and the company’s lead
independent director. “Paul’s vision has consistently been out in front
of industry shifts, and his strategic execution has positioned the
company at the center of the mobile-led, cross screen and programmatic
future of digital advertising.”

“Michael Barrett is an exceptional leader who has shown incredible skill
in leading companies and teams to big success in the digital advertising
industry,” said Wenda Millard, President of Medialink and member of

positioned, and there is no executive better suited to lead Millennial
Media’s next phase of growth. With Michael’s diverse expertise in
scaling advertising businesses in both the brand and programmatic
spaces, he will be instrumental in taking the company to the next level.”

time at the company, and within the industry,” said Michael Barrett.

building on the leadership position Paul and the team have created to
bring Millennial to new heights. I have long admired the company’s
ability to deliver superior monetization to its publishers and developer
partners and powerful ad solutions to its brand and performance
